These flat-field eyepieces were designed to provide an ultra-sharp, ultra-clear, crisp image from the center all the way to the edge of the field of view. The 15mm Ultima Edge eyepiece features fully multi-coated optics and an 8- element lens design, maximizing light transmission.

The Ultima Edge 15mm has a generous 65° field of view perfect for viewing planets, stars and the Moon’s surface.  This eyepiece provides good mid-power magnification, perfect for viewing the Moon’s surface and most deep sky objects.

Body

The 15mm Ultima Edge eyepiece’s main housing is machined from high grade aluminum with a black anodized outer surface.

Its 1.25″ mounting barrel is internally threaded to accept standard 1.25″ filters and adapters. It is compatible with 1.25” star diagonals and focusers. On the exterior of the eyepiece, you will find a uniquely designed, molded rubber grip ring for non-slip handling during observing sessions.

Viewing through the 18mm Ultima Edge eyepiece is comfortable for both eyeglass wearers and non-eyeglass wearers alike, thanks to the rubber eyecups and long eye relief of 16mm.
